5 out of 5 eggsFirePower ZX Series 1250W 80Plus Gold Fully-Modular High Performance ATX PC Power Supply

Pros: Ive had this PSU for almost four years, works like a champ! Ive gone through two motherboards and two GPU's and this thing is still fighting strong. Would recommend this to anyone wanting to make a high powered gaming PC

Cons: I wish there was a way i could thoroughly clean the inside without taking it apart. If only Fully modular meant FULLY modular lol.

5 out of 5 eggsSaw some negative comments so I'm here to negate some hate

Pros: Still running strong since 2012
Lots of Watts to have room for upgrades
Never had any trouble within all those years. I use my computer all day everyday for the most part.
Lots of powerlines for lots of hardware

Cons: Expensive

Other Thoughts: Remember guys. People usually don't rate an item if they are content with their purchase.
I do how ever regret getting such a powerful PSU because I really didn't need it.
I was thinking about how I would have Quad SLI or something but never got to it. LOL

Cons: Lasted only 3 1/2 years

2 out of 5 eggsGood Tech Support, Bad Tech

Pros: Customer support was very helpful through e-mail. Their website was very easy to navigate to determine how to remedy the issue. It included multiple troubleshooting techniques (some at a higher than normal knowledge level) that were easy to understand.

Cons: My knowledge of the inner-workings of power supplies is far inferior to the rest of the computer (they might as well run on magic). I can't say if it was DOA or something in my system or house caused the problem. But when i powered on my system for the first time (after reading and following the MB and power supply manuals) I heard an audible click which i assumed to be some sort of fuse inside the PSU.

Followed the troubleshooting techniques on the manufacturer's website, sent it in for repair/replacement, same thing happened with the next two attempts.

I couldn't tell if OCZ sent me a brand new one or a repaired power supply, so i can't say if it was a faulty repair or not. But I can say that when I re-installed my old power supply, my system powered up right away.

Other Thoughts: I ended up putting the power supply back in the box and sticking it in the back of my closet. Not worth my time to keep shipping it back to the manufacturer and risking damaging components on my system.

I want to mention that I was replacing an 850W PSU for this one (1250W).

2 out of 5 eggsNOISY!!!!

Pros: Does what any good power supply does and has been solid for the most part. But....

Cons: Very annoying coil while at high load and may be the reason some games crash a few minutes in. After working closely with EVGA premium tech support to determine if the problem is the 3 evga titans the Evga SR2 motherboard or the power supply, we narrowed it down to the whiny little ocz zx 1250watt power supply. I tried contacting OCZ for support and RMA but they NEVER answer phones or reply to emails or support tickets. Not happy with OCZ right now...

Other Thoughts: A+ certified IT Technician working in the biz for many years now.... I think I have earned the right to call OCZ out....

Manufacturer Response:

Dear BTG,

I am very sorry you have noticed coil whine between the ZX1250 and your 3 GTX Titans. Both the ZX1250 and the Titan(s) are great products - if the issue is originating from the ZX1250 OCZ will definitely assist and replace it if necessary.

It is possible you have contacted us or created a support ticket over the holiday observance period where just like EVGA, OCZ operates limited support hours. I am happy to assist you with this and will gladly expedite your support ticket (RMA) request. Please contact me using the email address provided below and provide the following information:

Phone Number
Ticket Number

After providing the requested information I will do whatever possible to bring this to a swift resolution. Thank you for your purchase and for sharing your feedback.

Kind Regards,

OCZ Technology Group

1 out of 5 eggsStay Away

Pros: It was a nice fully modular power supply.

Cons: 3 out of 4 of these have failed either completely or don't produce enough voltage to fire up the machines.

Other Thoughts: Based on our experience with these and OCZ's SSD's I would not recommend any OCZ product at this time.

Did you find this review helpful? Yes No

5 out of 5 eggsExcellent high-capacity supply

Pros: High power rating.
Mod cables are sleeved - black.
OCZ Support very good.

Cons: The socket for the power cable came loose from tension on the cable. I contacted OCZ support and they easily sent me a new unit as a replacement. As a loyal OCZ customer over many years, I will continue using their products because I know that their support staff care about the customers and keep me coming back for mooooar.

Other Thoughts: No lights or LEDs (personal preference).

1 out of 5 eggsskip it

Pros: A lot of power when it works

Cons: Owned it for less than a year . Computer completely shuts off randomly. Tested and narrowed it down to the Power supply.

Other Thoughts: Ocz will not honor their 5 year warranty without a receipt. The product has not even been on the market for 5 years. I'll stick to companies that honor their warranty from now on.

Manufacturer Response:

Dear Anonymous Consumer,

There seems to be a misunderstanding here. OCZ will honor all valid warranty claims. An original sales receipt or valid copy of the receipt is required to establish purchase date and original purchaser. You can easily obtain this by logging into your Newegg account and printing a copy. You can also take a screenshot or scan it then send it to us for verification. If I can help with this please contact me at the email address below and I will assist.

Kind Regards,

OCZ Technology Group
